Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0026] An interlocking device includes a sliding lock that controls opening and closing by sliding and a rotating lock that controls opening and closing by rotation. A linkage component with a stop block 11 and a limiting arc plate 10 is provided between the sliding lock and the rotating lock. A traction member that follows the rotation is provided on the rotating lock. Under the linear sliding drive of the sliding lock, the angle of the stop block 11 on the circumferential rotation path of the traction member is adjusted. The traction member can be engaged with the limiting arc plate 10 under the rotation drive of the rotating lock to limit the linear sliding of the sliding lock.

[0027] Through the linear sliding adjustment of the sliding lock, the stop block 11 is driven to be adjusted, so that the stop block 11 switches on the rotation path of the traction member. When the stop block 11 blocks its circumferential rotation path, the rotation angle of the rotating lock is restricted. When the stop block is misaligned with its circumferential rotation path, the rotating lock and the traction member can be rotationally adjusted. At this time, the traction member rotates to a position corresponding to the limiting arc plate 10, thereby restricting the linear sliding adjustment of the sliding lock, achieving the purpose of mutual interlocking.

[0028] Among them: The sliding lock includes a first lock rod 5 and a square shaft 4. The first lock rod 5 is fixed at one end of the square shaft 4. The linkage component is arranged at the other end of the square shaft 4. The square shaft 4 slides horizontally along multiple translation frames 2. Multiple translation frames 2 are fixed on the base 1, and multiple translation frames 2 are distributed at intervals.

[0029] The horizontal sliding installation of the square shaft 4 and the first lock rod 5 is realized by setting the translation frame 2.

[0030] The translation frame 2 is provided with a limiting component for the lateral sliding of the square shaft 4. The limiting component includes a swing arm 15, a first insertion rod 18 and a second insertion rod 19. At the position where the square shaft 4 is connected to the translation frame 2, a pair of swing arms 15 symmetrically distributed front and back are provided. The two ends of the swing arm 15 are respectively installed on the translation frame 2 through the first insertion rod 18 and the second insertion rod 19. One end of the swing arm 15 is rotatably installed on the side wall of the square shaft 4 through the first insertion rod 18, and the other ends of the pair of swing arms 15 distributed front and back are connected through the second insertion rod 19 inserted through. The translation frame 2 is provided with a horizontally distributed horizontal groove 17 and a vertically distributed vertical groove 16. The end of the first insertion rod 18 is slidably installed on the horizontal groove 17, and the end of the second insertion rod 19 is slidably installed on the vertical groove 16. The outer diameter of the first insertion rod 18 is equal to the width of the horizontal groove 17, and the outer diameter of the second insertion rod 19 is equal to the width of the vertical groove 16.

[0031] By setting the cooperation of the swing arm 15, the insertion rod and the groove, the square shaft 4 is installed on the translation frame 2, so as to ensure the sliding position of the square shaft 4, realize linear sliding, avoid deviation during driving, and at the same time limit the cooperation of the insertion rod and the groove to ensure the smoothness of sliding and avoid shaking and deviation up and down. At the same time, the length of the vertical groove 16 and the horizontal groove 17 is used to limit the sliding distance of the square shaft 4.

[0032] The rotation lock includes a rotatable second lock rod 6. The traction member is set as a limit rod 12, and the limit rod 12 is fixed at one end of the second lock rod 6 close to the linkage assembly. The linkage assembly includes a rotating shaft 8 and a rotating frame 3. The base 1 is provided with a rotating frame 3. The rotating frame 3 is arranged at a position perpendicular to the distribution direction of the multiple translation frames 2. The rotating shaft 8 is rotatably installed on the rotating frame 3 through a bearing. The upper end of the rotating shaft 8 is provided with a transmission assembly connected to the square shaft 4. Through the transmission assembly, the lateral sliding of the square shaft 4 drives the rotation of the rotating shaft 8, and the stop block 11 is fixed on the rotating shaft 8.

[0033] By setting the rotating frame 2, the rotation of the rotating shaft 8 is realized. Furthermore, by using the sliding of the square shaft 4, the rotating shaft 8 is driven to rotate synchronously, so as to realize the angle adjustment of the stop block 11 and the limit arc plate 10. Among them, the second lock rod 6 can only be rotated and adjusted within 90 degrees clockwise due to the limitation of the installation structure.

[0034] The end of the second lock rod 6 is provided with a swing rod 9. The limit rod 12 extends to the lower end of the swing rod 9. The end of the limit rod 12 is provided with a vertically bent hook plate. The middle section of the rotating shaft 8 is provided with a limit arc plate 10 that cooperates with the limit rod 12 to limit the sliding of the first lock rod 5. After the limit rod 12 rotates 90°, the hook plate at the end is parallel to the side wall of the limit arc plate 10.

[0035] By setting the hook plate, the cooperation between the limit rod 12 and the limit arc plate 10 is realized, so as to use the rotation lock to reversely lock the sliding lock.

[0036] The transmission assembly includes a connecting rod 7, a positioning slide rod 14 and a long groove 13. One end of the connecting rod 7 is fixedly installed at the upper end of the rotating shaft 8, and the other end of the connecting rod 7 extends to the upper end face of the square shaft 4. An open long groove 13 is provided at the end of the connecting rod 7. A positioning slide rod 14 is vertically arranged on the upper end face of the square shaft 4. The positioning slide rod 14 enters the long groove 13 along the opening, and the outer wall of the positioning slide rod 14 slides and fits against the inner wall of the long groove 13.

[0037] The transmission between the square shaft 4 and the rotating shaft 8 is realized by setting the transmission assembly.

[0038] Working principle: First, as Figure 1 shown, when the first locking rod 5 and the second locking rod 6 are in the initial state, due to the limiting effect of the stop block 11 at this time, the rotation of the limiting rod 12 is blocked, so that the second locking rod 6 cannot rotate in this state. At this time, the sliding lock limits the adjustment of the rotating lock.

[0039] During the adjustment process, first drive the first locking rod 5 to slide horizontally, driving the square shaft 4 to slide horizontally on the translation frame 2. During the sliding process, since the first plug rod 18 slides along the transverse groove 17, it ensures the smooth sliding of the square shaft 4 and avoids vertical deviation. The position of the square shaft 4 is further limited by the cooperation of the second plug rod 19 and the vertical groove 16, as Figure 2 shown;

[0040] As the square shaft 4 slides horizontally, the positioning slide rod 14 laterally presses the long groove 13 and slides outward toward the open end in the long groove 13, thereby synchronously driving one end of the connecting rod 7 to shift, pulling the rotating shaft 8 to rotate synchronously, realizing the shift and misalignment of the stop block 11, and the limiting arc plate 10 deflects synchronously. At this time, the second locking rod 6 can rotate 90°, so that the limiting rod 12 rotates to the upper end of the stop block 11, and the hook plate at the end of the limiting rod 12 faces the side wall of the limiting arc plate 10, as Figure 3 shown;

[0041] At this time, if the first locking rod 5 slides and resets in the reverse direction, it will drive the limiting arc plate 10 to press against the hook plate at the end of the limiting rod 12, thereby restricting the rotation of the rotating shaft 8, and further achieving the purpose of restricting the reset of the first locking rod 5. At this time, the rotating lock reversely locks the adjustment of the sliding lock.

[0042] When the rotating lock deflects, the limiting rod 12 and the limiting arc plate 10 are misaligned. At this time, the first locking rod 5 can perform a reset movement, which makes the stop block 11 reset in the reverse direction. At this time, the stop block 11 blocks the path of the limiting rod 12 rotating and resetting, restricting the reset of the second locking rod 6, achieving the purpose of restricting the rotation angle of the second locking rod 6. When the second locking rod 6 needs to be adjusted, it is necessary to first drive the square shaft 4 to slide horizontally by using the first locking rod 5, driving the rotating shaft 8 to rotate, so that after the stop block 11 is misaligned, the second locking rod 6 can continue to rotate and adjust, as Figure 4 shown.

[0043] In this way, an interlocking relationship is formed between the sliding lock and the rotating lock, that is, when the sliding lock is in the initial position, the rotation of the rotating lock in the current state can be restricted, and when the rotating lock is in the rotating position, the reset of the sliding lock can be restricted.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
